| Abstract: | An embedded system architecture for image acquisition and processing, based on a Nios II soft-core processor, is presented in this paper, where high speed data transmissions among image acquisition buffer, image processing buffer and image display buffer are implemented with Avalon-bus streaming interfaces. Emphatically, custom and design of main composition modules for the system are described, and an example for using the system is given. |
